IMPROVEMENT INJSRESSURE REGULATO-RS AND INDICATORS.

Speciication forming part of Letters Patent No. 221,885, dated November 18, 1879 application filed October 29, 1879.

To alllwhom it may concern:

Be it known that I, FREDERICK W. Winsu- BROOK, of the city, county, and State of New York, have invented certain new and useful Improvements in Pressure Regulators and Indicators, of which the following is a specification.

Ihe object of my invention is to construct an improved pressure regulator and indicator; and it consists in the construction and arrangement of the parts, as will be more dednitely described hereinafter, reference being had to the accompanying drawings and the letters of reference marked thereon.

In the accompanying drawings, Figure I is a vertical longitudinal section of my pressureregulator. Fig. II is an end view ofthe same, showing the indicator-gage.

In the drawings, A represents the body of my device, having four branches, the lower one, a, being screwed or tapped into a vessel containing the liuid under pressure, while the branch b is connected with a pipe.

In the branch c is arranged a diaphragm and valve connected to a weighted lever, spring, or equivalent. At the outer end of this branch is a suitable cock, O, to allow the air or gas to escape when desired. In the branch c arearranged two curved channels, D and E, the latter forming at its upper end a seat for the valve c, which is provided with suitable packing.

The valve has a stem, J, and to this is connected a lever, F, having suitable gradua` tions upon it, and an adjustable weight, G. The lever is pivoted at the upper end of the branch d. l

On `the stem J is secured, just above the valve e, a diaphragm, f, the edges of which are clamped between the iianges g h. Above the diaphragm is secured the cap i by suitable bolts or screws.

The upper end of the branch d is provided with a curved pipe, H, to which a mercurygage, I, is secured with its open branch, while the curved closed end is secured to a plate having flanges for thev protection of the gage, and the graduations and numbers to indicate the amount of pressure in the vessel.

The branch b is provided with a cock, B, and this branch connects to a pressure-pump or other vessel containing compressed air; and when it is desired to rack oft' the liquid,

whatever it may be, whether water, beer, ale,

or other liquids, the cock B is opened and the cock C is closed.

As it is desired to retain the absorbed gases in the liquid, therefore the space formed during the process of racking off is always filled with compressed air or gas, suflcient for the retention of the absorbed gases in the liquid, and for the racking ontl of the same.

An important fea-ture of my invention is the valve-chamber, with its diaphragm andvalve, which form together a differential pistonvalve. the valve, so as to prevent the sticking of the valve on its seat, while at the same time the operation of the valve is made very sensitive by the pressure from the vessel containing the liquid against the under side of the diaphragm.

'Ihe weighted lever F tends `to close the valve against the pressure on the diaphragm, and will, with the aid of the outtlowing gas through the valve-seat E, close the valve instantaneously when the equilibrium of press ure on the diaphragm is disturbed.

To the end of the cock C suitable pipes may be attached, by which the escaping gas may be carried to any desired place.

I am aware that pressure-regulators provided with diaphragms have been heretofore used for regulating the pressure of liquids in vessels; but these differ entirely in construction and operation from mine, and I do not therefore broadly claim such 5 but,

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is l. A pressure-regulator consisting of the body A, provided with a valve-chamber, A', having channels l) E and a valve, c, connected to a weighted diaphragm, f, all constructed and arranged for operation substantially as shown and specified.

2. A pressure-regulator consisting of the body `A, with a valve-chamber, A', having channels D E and a valve, c, connected to a weighted diaphragm, j', and branches b and c, provided with the cocks B-` and O, all constructed and arranged as shown and described.

The diaphragm has a larger area than 3. A pressure-regulator consisting` of the In testimony that I claim the above I here- -body A, with a valve-chamber, A', having unto set my hand. *.v-Channels D E and valve e connected to a weighted diaphragm, f, in cOInbination with F' W WIESEBROCK the indicating mercury-gage I, all constructed Witnesses: and arranged for operation, as shown and CHAS.
